Tiny pinkish apothecia on Fagus bark

Hello! These tiny (0.3-0.4 mm) greyish yellow/pinkish apos were found on thick bark, hidden under the thin outer bark of large rotting trunk of Fagus sylvatica lying on the ground. Attached to the substrate on a narrow, substipitate base. Outer surface with very short, pale protruding cells (appearing downy). Excipulum with large brownish, prismatic cells, gradually transitioning into paler, clavate cells towards the exterior. Asci IKI-, mostly ca. 50 x 5 microns, with croziers. Paraphyses cylindrical, without guttules, non-septate, 1.5 - 2 microns across. Spores elliptical, with a small guttule near each pole, ca. 5-6 x 1.5-2 microns.
Images from fresh material, in water.
Are we in Mollisia? Suggestions appreciated.
Thanks!

Re : Tiny pinkish apothecia on Fagus bark
This could be Pyrenopeziza (Mollisia) caespiticia or alternatively Mollisia sublividula. The latter has yellowish VBs in te paraphyses which is probably not the case in your fungus.

Re : Tiny pinkish apothecia on Fagus bark
You're right - no yellowish VBs in the paraphyses. I have compared with P. caespiticia and that is indeed a good match. I have seen that species once before, but then immature apothecia in erumpent clusters. Thanks a lot!
